Nature and Science of Sleep

Key Finding: 12° inclined sleeping reduced snoring by 7%, nighttime awakenings by 4%, and increased deep sleep by 5%.
View Summary

This in-home intervention study examined the effects of sleeping at a 12° incline using an adjustable bed base compared to flat sleeping in adults who snore.

Key findings:

  • 7% reduction in snoring
  • 4% decrease in nighttime awakenings
  • 5% increase in deep sleep
  • Improved subjective restfulness ratings

The study suggests inclined sleeping has potential as a non-obtrusive means of reducing snoring and improving sleep quality.

Sleep and Breathing

Key Finding: 7.5° head elevation reduced mild-moderate OSA severity by 31.8% on average.
View Summary

This study examined how head-of-bed elevation affects obstructive sleep apnea severity in patients with mild to moderate OSA.

Key findings:

  • 7.5° incline reduced OSA severity by 31.8% average
  • Improved oxygen saturation during sleep
  • Reduced apnea-hypopnea index
  • May be useful adjunct to other OSA treatments

The researchers note positional therapy (including bed elevation) is an underutilized approach for mild-moderate OSA.

Evidence Assessment

C Limited Evidence

This intervention has preliminary evidence from early-stage research, mechanistic studies, or observational data. More rigorous trials are needed.
